      Hello Jaco
      I had an experience of unstable sate of USB/Si570 .
      Did you set your RXTX board into metal case?
      If so, please check USB-Si570 land of PCB is isolated to case-GND.
      The hole of USB-Si570 land(the one of corner 4holes ) for setting PCB
      to case should be isolated by insulated spacer, bolt.
      And also make sure if USB Jack/plug is isolated from metal case.
